A group of scientists discovered a new element that gives the properties of inert gases they should palace the new element in the periodic table with the elements of:
Correct answer: D. p-block
- A. s-block
- B. d-block
- C. f-block
- D. p-block
Explanation
In the periodic table, elements with similar properties are grouped in blocks based on their electronic configurations. The inert gases, also known as noble gases, are located in the p-block of the periodic table. The p-block elements consist of groups 13 to 18, which include elements such as helium, neon, argon, and so on. These elements have full valence electron shells, making them chemically stable and relatively unreactive. Therefore, when scientists discover a new element that exhibits the properties of inert gases, it should be placed in the p-block of the periodic table.

About Blocks of the Periodic Table
Electron configurations divide elements into s, p, d and f blocks according to the subshell receiving the last electron. Work includes the positions, valence-shell configurations and general properties of s-block and p-block elements, along with periodic trends in atomic size, ionisation energy, electron affinity and electronegativity.
